Xiphos

Overview

Xiphos is a classical alpha-beta chess engine with a handcrafted evaluation function. The project is inspired by Garry Kasparov's "Deep Thinking". This fantastic book has evoked my childhood passion, computer chess. I was wondering how hard it could be to develop an engine strong enough to surpass the legendary Deep Blue, so I gave it a try.

The latest release, including the binaries for various platforms, can be found here.
